Hello, I was asked by Rudolf to give the source code of my DOS/WIN/LINUX universal SPI FlashROM programming utility. So here's it: http://www.volny.cz/rayer/programm/spipgm.c Feel free to integrate it into your flashrom utility (btw I would be interested in DOS/WIN32 port)
Note: you will need to accomodate low-level function for I/O acces, this layer is NOT included. Under linux it should be enough to rise IOPL and then use inportb/ outportb (beware arguments order, I use DJGPP syntax). Sorry for the comments, my mind is randomly switching between cz/en :)

Hi RayeR,
thank you very much for the source code!

flashrom is GPL. Is that OK for you?

Yes, we will have to write such a layer anyway.

Thanks for the hint!

No problem, my mind is randomly switching between de/en, so I know how to make the best out of such comments. And your code is very clean, so I don't need most of the comments.

I found some time to check your chip ID list against my chip ID database and I have a few questions:
The following definition conflicts with the definition in my database for SST25VF032B. SST25VF032 0x2542 Maybe the SST25VF032 and the SST25VF032B have different IDs. Do you have a datasheet for the SST25VF032?
Do you know where I can get data sheets for the following chips? Google turns up nothing. SST25VF064 0x2543 SST25VF128 0x2544 SST26VF064 0x2603

Go to the SST web site. If they are not available there, they are not available period. I would suggest to not bother with code until you can get the documentation from the source.

OK, will do.

Below are some linux macros I used there.

just iopl(3); should be need but it requires root privileges.

Hi RayeR,
thanks for the quick response! The explanations are very valuable for me.

I could not find any of the chips in the list above in your collection. May I ask where you found the IDs?

I don't remember, maybe just I made a guess how the JID would continue in curent product line to be prepared to future. It's going similar with other manufacturers. If you see some mismatch and have you proved with some tech. document tell me what to change.
